New video shows Anthony Acevedo, 20, and Jose Alarcon Sanchez, 18, firing gunshots across a Dallas bridge on New Year’s, leading to their eventual arrest.

Detectives are working to determine why the man was outside with a gun as the investigation continues.

Officers responded to reports of gunfire on Jan. 17 in the 1200 block of Presidio Avenue in southern Dallas. They found that 31-year-old Oscar Saldana was involved in a disturbance in the area when he allegedly shot a weapon into the ground, WFAA previously reported.
